Move An Asteroid 2008 Technical Paper Winners Annouced - Planetary Defense - From the post:
The Space Generation Advisory Council, the world’s largest group representing youth perspectives on space exploration to the United Nations and national space programs today announced the winners of an international youth technical paper competition to develop unique and innovative concepts for how to deflect an asteroid or comet that could impact the Earth (referred to as mitigation).
First place in the competition is awarded to Mary D'Souza of the Department of Mechanical Engineering at the University of Queensland in Australia for her paper entitled “A Body Solar Sail Concept for the Deflection of 99942 Apophis.” Ms. D'Souza’s concept involves wrapping an asteroid in a reflective film (referred to as a “body” solar sail).
Second place is awarded to Mr. Andrew Bacon of the Department of Electronic and Electrical Engineering at the University of Bath in Bath, United Kingdom for his paper entitled “The Use of Electromechanical Resonators for the Mitigation of Earth Threatening Asteroids and Comets.”
